What is the steel used for this Sharpfinger?

[Charlie Mike]

I need to send this out for HT.

 

[Charlie Mike]

I'm pretty sure it's stainless based on the lack of sparks.

 

[orvet]

Probably 440. Phil may know for certain.

No, this is 1095 Carbon Steel

CM,

Was it ground when you got it?

No, it was a blank and I cut the choil.

 

[Phil Gibbs]

It is Carbon Steel; 0170-6C

You need to find someone that has Liquid Heat Treat capabilities!

OK Phil, Liquid Heat Treat Capabilities is a new term to me.
Please elaborate!

Thank you!

Hardened in molten lead or molten salt.
1550 F will suffice.
Fast quench in agitated oil.
Temper twice.

Conventional oven heat treat of carbon steels is like microwaving a Filet Mignon.
Perhaps edible, but massive lost potential!
IMHO of course.

Phil, for some reason this has me fascinated today. I have often wondered about how companies like Camillus, Case, Schrade and others heat treat the massive quantity of knives they produced.
Can you walk us through the process?
Edit: I found this. Very interesting.

The catalogs on this site have pictures of the knife making process. It is how it was done at that time but it is a good read. http://www.collectors-of-camillus.us/Western/Western.htm it is Western knives but I am sure the process was the same.

 

[Mack]

Thank you. That is very informative.

Matt & Phil: are you guys sure that knife blank isn't already heat treated? I have about thirty Camillus knife blanks here, and I thought that the ones with tang stamps were already heat treated. Might be a wrong assumption on my part. How can I tell for sure what's heat treated and what's not?

Tang stamp happens when blade is soft before heat treat.
Blade color is not an indicator as some blades were stress relieved & annealed prior to tang stamping!

Only way to be sure, try a file on the un-ground section of the edge.

If the blade is ground, it is heat treated.

I hope this helps!
